Sturmey Archer Single Speed Freewheel

[20130814]

Hi,

I have an old 700c rear wheel with an old fashioned threaded shimano freewheel on it, much like this:

I'd like to remove it and put a single speed freewheel on it - like this:

I wondered two things:

1. Would that type of thread be the same as on the Shimano freewheel?
2. Would I need to get a different chain, and presumably, might that different chain not fit the chainset?

The chainset is much the same as is on this bike:

Any advice much appreciated.

Thanks

Jim

the link you have posted is for a cassette, not a screw-on freewheel.

If you have a screw-on freewheel then yes a singlespeed freewheel will screw on the same hub, albeit at a wrong/weird chainline.

If you really have a cassette, then it won't.

A 1/8" chain is required for the singlespeed freewheel you have linked to. The chances are that this will run OK on a 3/32" chainring meant for a derailleur chain, but that it will be more likely to fall off than if you use a proper 1/8" chainring.

You can buy a 3/32 single speed freewheel to match your chainset.

If I were doing this I would rearrange the spacers on the rear wheel to get the chainline right and then re-dish the wheel. If fact I would say that this would be essential.
